Abstract Early life stage (ELS) studies with brown trout(Salmo trutta f. fario L.) andstone loach (Barbatula barbatula L.)were performed between 1995 and 2000 toevaluate embryotoxic potentials in twodifferently polluted streams in southwestGermany. With both species, semistatic exposureexperiments with water samples and sedimenteluates were conducted in the laboratory.Additionally, brown trout ELS tests wereperformed in flow-through systems in thesemi-field and in the field. Thus, differentlevels of complexity of environmentalconditions were addressed which allowed thestudy of effects of xenobiotic contamination,temperature, and sediments on the success ofembryonic development. Additionally, effects ofwater from the polluted stream on fertilizationof brown trout eggs were determined. In themore polluted stream, xenobiotics caused anembryotoxic potential for both brown trout andstone loach, and viability of exposed browntrout eggs was drastically reduced by suspendedsolids in the water which covered the eggs.Additionally, fertilization rates of browntrout eggs were significantly decreased inwater of the more polluted stream. In the lesspolluted stream, low water temperature andinfestations by protozoic ectoparasites causedmortality of embryos. In this stream, pollutionand sediment effects were not observed. Resultsmade evident that in the more polluted streamrecruitment of brown trout was drasticallyimpaired.
